Privacy Policy

Privacy Policy for BulkPicTools. We prioritize your privacy—your images are never uploaded to servers and are processed locally in your browser.

Last updated: 1/1/2026

At BulkPicTools, we consider user privacy our highest priority. This Privacy Policy is designed to clearly explain how we handle information when you use our website and tools.

Our Core Promise: Your Files Never Leave Your Device

BulkPicTools is different from traditional online image editors. We utilize advanced WebAssembly (WASM) technology, which allows all image processing operations (Batch Crop, Compress, Convert, etc.) to run directly on your own device (in your browser).

This means:

  1. Zero Uploads: Your images are never transmitted to our servers or any cloud storage.
  2. Zero Storage: We cannot view, copy, or store your images because they never leave your computer.
  3. 100% Private: Our tools function securely even without an active internet connection (offline mode).

  • Access origin (Country/Region level only)
  • Page load speeds and error reports

We do not use cookies to track your personal browsing history, nor do we sell user data.

Children's Privacy

Our services are not directed to children under the age of 13. Since we process files locally and do not require account registration, we do not knowingly collect personal information from children.

  2. Switch to the "Network" tab.
